Salt. It's to do with the bonding. Sodium chloride forms rigid crystals with ionic bonds so it's one large molecule in effect (the chemical formula NaCl really just shows the ratio of atoms). Glucose has separate molecules that aren't bonded to each other very strongly so it doesn't take much heat energy to separate the molecules from each other.
Salt melts ice faster than sugar and chalk because salt lowers the freezing point of water. When salt is added to ice, it disrupts the balance between the solid and liquid states, causing the ice to melt more quickly. Sugar and chalk do not have the same effect on lowering the freezing point of water.
You need to determine what you think will melt the fastest, and that will be your hypothesis. If you think that pepper will melt it faster, you would say "My hypothesis is that the pepper will melt ice faster than the other variables (sand, salt, and sugar)."
Sugar crystals tend to grow faster than salt crystals because sugar molecules are larger and more prone to clustering together, allowing for quicker crystal formation. Additionally, sugar is more soluble in water compared to salt, which also contributes to faster crystal growth.
No, Salt will not dissolve because the Ethanol is less dense then the salt so in order to make it dissolve u have to have a greater density then a smaller density. Ex. Sugar and water. When you stir it mixes and mixes all of the particles together. And same for the Sugar.
Yes, salt really does melt ice, but it can refreeze if the temperature is low enough. The idea is to create a salt-water mix that has a much lower freezing point. Generally, rock salt may be used, occasionally with other binders such as sand. An alternative to using granular salt is to spray on a solution of brine, sometimes mixed with other minerals or chemicals (usually not ordinary antifreeze because it is ecologically toxic).
By heating sugar is decomposed at approx. 180 oC.
Chalk
Salt will melt first.
Sugar. You can caramelize sugar on a home stove quite easily. Salt's melting temperature, by contrast, is orders of magnitude higher
Sugar. Salt often slows down the process of melting, so sugar is what would melt it faster.
Salt
sugar
Salt, obviously.
Lead melts more easily than salt or lime. Not the fruit.
More sugar can dissolve in water than salt.
Sugar melts faster than salt because sugar has a lower melting point than salt. Sugar typically begins to melt at around 320°F (160°C), whereas salt does not fully melt until it reaches temperatures exceeding 1,472°F (800°C).
Both salt and sugar lower the freezing point of water, causing ice to melt at a lower temperature than it would in pure water. However, salt is more effective at lowering the freezing point than sugar, so it will melt ice faster at the same temperature. The presence of salt or sugar also disrupts the structure of the ice, further accelerating the melting process.
